Calculated value displayed in DWC as sensor

[CNCModeller]

Hi All,
I'm wanting to display the dew point on DWC as a sensor value.

I have a DHT22 reading properly and am hoping to use daemon.g to calculate dew point from the temperature and humidity.

My question is can I display that result as a virtual sensor value in DWC alongside the DHT22 values. I'm probably missing something obvious in the documentation but nothing is leaping out at me.

Any constructive thoughts would be much appreciated.

All the best.

@CNCModeller the only way I'm aware of would be use btncmd to display the value assuming you're writing it to a global variable

@jay_s_uk Thanks, will take a look

@CNCModeller Just a FYI, I needed to accurately read humidity at different points for a project so I bought five DHT22 and compared them. With them all plugged into the same breadboard next to each other, I checked the readings and got a range of between 31 and 38 RH. According to the data sheet, the accuracy should be +/- 2% (max +/-5%). So spread of +/- 3.5%RH out of around 35%RH is about +/- 10% which is way outside the claimed accuracy according to the data sheet.
